I have also said H. x hybridus is perfect for dry shade, as I grow sweeps of them intermingled with bulbs and other herbaceous plants under my pleached hornbeams on the shady side of a beech hedge. The soil is extraordinarily dry, being in the south east and on a shallow limestone brash. They look good there, a medley of white to pink to dark purples. However, Mike says they do better in areas of winter sun.
Other misinformation, according to Mike, is that the plants are difficult to move. They are easy, he insists, provided you do this between April and August. Dig them up, divide if you want to and move to pastures new. Mike grows a range of hellebores in rough grass at the base of hedges in the wilder areas of his garden and farm. His wife strims the grass in November and then the hellebores can be enjoyed.
